Project Abstract Additive manufacturing, particularly metal powder bed systems, offer great opportunities to develop novel parts with mechanical properties far different from that achievable in traditional manufacturing. One such application are lattice structures which can reduce weight while maintaining similar strength to a solid part. Tensile and compressive samples utilizing 3D lattice structures will be tested using a numerical model and the best performing structures will be used in experimental testing using samples produced via DMLS printing. After validation of models, the overall best performing structure, as measured by yield strength per unit weight, will be used to manufacture parts, such as a differential for the University of the District of Columbia NASA Human Exploration Rover.
